Bscan (Boundary Scan) is a technology used for chip testing and debugging, mainly for detecting and diagnosing interconnect faults inside chips or on PCBs (printed circuit boards).

When testing IOH and IOL, it is necessary to set VOL and VOL. When testing VOH and VOL, it is necessary to set IOH and IOL.

The experimental condition strength of HAST at 130 ℃ 85% RH for 96 hours is higher than that of THB at 85 ℃ 85% RH for 1000 hours.

In ICP etching equipment, the induction coil is generally located above or around the reaction chamber. When RF current passes through the coil, a periodically changing magnetic field is generated.

Reliability testing refers to determining and verifying the reliability of a product through experimentation. Research on identifying weak links in products with limited samples, time, and usage costs. Reliability testing is a general term for various tests conducted to understand, evaluate, analyze, and improve the reliability of products.

Digital Logic Testing is mainly used to detect the digital circuit part of a chip, ensuring its logic function, timing characteristics, and structural integrity.

Environmental Stress Screen (ESS) is the process of accelerating the exposure of potential defects within electronic or electromechanical products by applying reasonable environmental stress (such as temperature cycling, random vibration, etc.) or electrical stress within the design range.

Burn in is a specially designed test vector used to activate various modules inside the chip during aging testing, ensuring that the chip can operate normally under accelerated stress conditions such as high temperature and high voltage, thereby detecting potential defects and faults in advance and improving the reliability and quality of the chip.
